Sand painting training costs thousands of dollars, which is not a small investment for beginners and enthusiasts. And this kind of training is like learning to play billiards, telling you the rules. You still have to practice your skills yourself. Sand painting is a test of practical ability, not how much money you can learn. As long as sand painting knows how to get started, the next step is to practice hard. Thinking by yourself is far better than attending any training.
Personal suggestions, please refer to. Taobao now has a sand painting training class, which is a book, and it only needs 69 yuan. Compared with the training fee of several thousand yuan, you can at least get started by yourself. The specific name of Taobao shop is very domineering, so I won't say it, lest it be an advertisement. Search on Taobao yourself.
